Abstract: 本发明揭示了一种数字处理装置,它具有平滑斩波功能(25)和使用它的数字音乐语音合成装置。当一个或者多个数字值输入数字处理装置,并激励了平滑斩波模式时,由于装置的内部结果值在输出之前缩小,故避免了数字值处理过程中的溢出。内部结果值的缩小根据内部结果值的增加而连续增加,从而避免了溢出。例如,如果数字处理装置在数字音乐语音形成装置中执行两个数字操作数的求和,结果语音信号坡度的时间特性是平滑的,由此改进了声音动态,并在声音再现中避免了声音畸变。

Abstract: 1,052,564. Pipe brackets. MESSRS. A. RAYMOND. Sept. 16, 1965 [Oct. 7, 1964], No. 39600/65. Heading A4B. [Also in Division E2] A resilient fastener for attaching an elongate and relatively rigid member 10 to a support 4 is formed from a single strip of material to U-shape so as to have two arms 8 joined by a web 1, the web being adapted for attachment to the support and the arms being normally inclined outwardly from the web, each arm having a slot 9 extending transversely from one or other of its side edges to engage the elongate member, the two arms being resiliently movable into a position in which they are generally parallel and the shape and size of the innermost portion of the slot in each arm corresponding substantially to a section taken through the elongate member in a plane parallel to the respective arm when the arm is in its normal position and the axis of the elongate member passes approximately centrally through the innermost portions of the slots. In the construction shown the web is provided with a pair of lugs 2 the free ends of which are V-shaped and which are adapted to engage a support 4 in the form of a cylindrical pin in a manner such that the fastener can be rotated around the pin. The slots open out of opposite side edges of the arms 8 and this arrangement enables the fastener to be rotated into engagement with the elongate member which as shown is a tube. Each slot has an overhang 11 in its length which when the arms are in their normal inclined position prevent rotation of the fastener to release the elongate member. In a modification (not shown) the transverse end portions of the arms are rolled over to prevent damage to the user's fingers when the arms are manually moved together.

An adjustable stop 64 limits the amount of turning of the wheel by altering the last motion of lever 51 before contacting arm 50 and a spring 57 returns arm 50 to the stop. Lever 51 also open a nozzle flap 65. A casing cap 7 is unlocked by screw device 12 and allows the casing 15 to hinge forward on pivot 56 for replacing the cartridge. The tape or wheel may have an indication thereon when the cartridge is empty or a window 68 allows the plunger to be seen if the cartridge is transparent.

In the examples the aromatics are benzene, toluene, m-xylene and p-xylene; the alkylating agents are ethylene, propylene, butene-1, butene-2, isobutene, octene-1, octadecene-1, butadiene, isopropyl chloride and bromide, and tert.-butyl chloride and bromide; and the catalysts are mixtures of TiCl 4  with diethyl zinc or diphenyl zinc, and a mixture of TiBr 4  with diethyl zinc. The products include mono- and poly-alkylates.

Abstract: 1,232,747. Electron beam irradiation apparatus. T.I. (GROUP SERVICES) Ltd. 16 April, 1970 [18 April, 1969], No. 19921/69. Heading H1D. An electron beam irradiation apparatus for irradiating material such as paint which is moved past the apparatus, is provided with at least four separate windows along the line of travel, the beam being scanned to emerge from each window in turn. The scanning waveform may be such that the beam repeatedly passes through each window in turn in one direction (Fig. 2, not shown) or such that the beam passes along the line of windows and back again (Fig. 3, not shown) ; in either case the beam dwells at each required window and then jumps rapidly to the next one. The scanning may be electrostatic (as illustrated) or magnetic, and the beam may be scanned transversely to cover the width of the work as an alternative to using a wide beam. The scanning waveforms may be linked to the EHT supply to avoid mis-registration if the latter varies and may be synchronized with the mains supply to minimize variations in electron intensity from point to point in the scanning. The speed of transport of the work should be so related to the scanning speed that each element of the work is irradiated several times at each window. In the example shown there are six windows, but there may be as many as twelve ; the part doses delivered to each part of the work should be separated in time by intervals similar to the free radical half-lifetime of the reaction being induced.

Abstract: 1,239,355. Adjusting combustible gases. BLACK, SIVALLS & BRYSON Inc. 2 Feb., 1970 [10 Feb., 1969], No. 4960/70. Heading C5E. [Also in Division F4] A method of controlling the hydrocarbon content of a gas stream, e.g. of a natural gas stream 10 before its delivery to a pipeline, comprises cooling the stream with an expanded refrigerant stream 22 at 18 to condense undesired components in the stream 10, separating the condensed components at 40 to leave a residue gas stream 50, compressing the expanded refrigerant stream at 30 and heating the residue stream at 34 with the compressed refrigerant. An expansion valve 24 in the refrigerant circuit is regulated by a liquid level controller 26, and the compressor 30 is controlled by a temperatureresponsive element 52 on the separator 40.

Abstract: 1,252,508. Filaments and films. FURUKAWA DENKI KOGYO K.K. 23 Oct., 1969 [23 Oct., 1968 (2); 23 April, 1969], No. 51911/69. Heading B5B. [Also in Division C3] A solution of synthetic resin which may be used to form fibres and films comprises from 2 to 15% by weight of certain linear or non-linear polyoxadiazole and/or polyhydrazide resins dissolved in sulphuric acid having a concentration of from 78 to 110% by weight. The resin may be a polyoxadiazole having repeating units of formula or a poly (N-substituted hydrazide) having repeating units of formula or a copolymeric resin having repeating units of formula where R and R<SP>1</SP> are bivalent aromatic residues and R<SP>11</SP> is an alkyl, cycloalkyl or aralkyl group having 1 to 7 carbon atoms, the molecular weight of the resin being such that it has an inherent viscosity of more than 0À04 in a 0À5 gm/dl. resin solution in 95% by weight sulphuric acid at 30‹ C. Fibres are obtained by extruding the solution into a coagulating bath, and films are obtained by pouring the solution on glass plates and dipping the plates into a coagulating bath. The coagulating bath comprises (a) 10 to 68% by weight aqueous solution of sulphuric acid, (b) 10 to 80% by weight aqueous solution of phosphoric acid, (c) 10 to 55% by weight aqueous solution of nitric acid, (d) 60 to 100% by weight aqueous solution of an aliphatic carboxylic acid having a pKa (25‹ C.) of less than 3À8, or (e) a mixture of these solutions. The resin solution and/or the coagulating bath also may contain an inorganic salt. Examples are given in which filaments are stretched, immediately after coagulation, in hot or cold water or hot or cold air and films are biaxially stretched in the wet state.
